Shortly after sunrise on the morning of February 1, 2003, Doug Hurley waited on the long runway at Kennedy Space Center for a vehicle that would never come.

Only recently graduated to becoming a full-fledged astronaut, one of Hurley’s first tasks was serving as a “Cape Crusader” for the corps, meaning he watched out for the Astronaut Office’s interests in Florida. On this morning, he was part of a small cadre of astronauts to greet seven returning crew members on board the space shuttle Columbia.

As he waited, Columbia broke into pieces as it passed over Texas and other southern United States, along its ground track to Florida. Hurley’s friends died as their spacecraft burned up and broke apart during their reentry to Earth’s atmosphere. From the beginning of his career, then, Doug Hurley profoundly understood the risks of the profession he had just entered into.
